OK The WPPC arrived a few days ago and I performed the water test. It passed with flying colors. That night I used the cooker as a stockpot to make some mac and cheese from a mix. Its been super hot this week and I have been lazy LOL. It worked great. But... the next day after washing the cooking pot I noticed markings on the inside of the pot where I used a spoon to remove the cooked mac and cheese. I used a plastic spoon so I have no idea why these markings occured. I like the design of the cooker but to be honest they could have made a better remove able cookpot. Its not heavy and I suspect the non stick may end up coming off eventually. I am considering ordering a replacement cook pot to have in the event this happens. I will be using it alot I am sure as it is versitle!
